CHARLES E. PEEGIVZAL, OF SPBIPTGFIELD, MASSACHUSETTS.

CONVERTIBLE SEAT AND BED.

To a'll whom it may concern:

1 Be it known that 1, CHARLES F. Pnncxvan, a citizen of the United States of America, and resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful. Improvementsin Convertible Seats and Beds, of which the following is a full, clear, and exact description.

This invention relates to convertible seats, and beds, of a character comprising parts to constitute amain support or body, a seat, and a back for a seat or couch, with interconnecting means whereby the parts may be constrained to have movements inrelation to each other so that the seat or couch maybe transformed to a bed, and thereafter restored to the condition and aspect of a seat, lounge or clavenport.

An object of the present invention is to improve the arrangements of a main or body frame, an intermediate frame slidable in relation to the main frame, a seat frame, and a back forming frame, and the connections between one and another of the frames for the roduction'of the convertible seat and bed which is of simplified character and susceptible c unusually eas and convenient operation for effecting t e changes from seat to bed, and vice versa.

Another object is to provide a convertible.

couch bed which is so sectionally made, and adapted to be connected and disconnected, that the piece of furniture is available as a. full length lounge, divan or davenport; as

. two separate chairs or seats; as a half width bed, with a soft at the side of the head portion of such half width bed,-or with a seat disconnected and removedfrom the half width bed; "as a full Width bed; or as half width or twin beds, capable of being separated one from another by a little or great .a distance asmay be desired.

And fiirther objects of the invention are attained in and by the organization of the parts-za1iddevices as hereinafter rendered ma ifest.

T ie fpresent invention is described in conjunction ,with the accompanying drawings.

and is-iset forh in the elain'as.

In the drawings 1 v V Figure 1 is a perspective view sl'aowingg; the eotlch, lounge.or davenport, sectionally made,jone of the'scctions thereof being in its 'coinpacted or seat forming 'condition,

Specification of Letters Patent.

Application filed March 21, 1918. Serial No. 85,70

Patented Dec. 4, 1917.

While the other is opened out and extended to form a half width bed. i

Fig. 2 is a sectional elevation through one of the. sections or halves of the convertible their partially opened and extended relations.

Fig. 4 is a similar sectional elevation but showing the parts as in their fully opened and extended relation to form a bed.

Referring to the drawings, A re resents a-niain or body frame, of a low x-like form, both open upwardli and open at its front.

For the convertible couch and bed, this body frame is made of half the width of a. full width bed. \vhichdimension is one rorresponding to a half length of the couch or divan: and a pair of such body frames and of all of the parts to form half width beds, or seats or chairs having widths which are equal to half the length of the lounge, which are directly or indirectly connected to each of the main frames are employed in a mannerto be attachable and dlsconnectible for the purposes of this invention.

B represents theintermediate frame, so termed for the reason that when slid out from the main frame it has its position intermediately between the head and foot portions of the bed.

The combination and arrangement of the main and intermediate frames are substantially the same comprised in the couvertible seat and bed formin the subject matter of Letters Patent 0 v the United States issued to me June 8, 1909, No.924,374, as well also in a general way as are the relative combinations and arrangements with .the main and intermediate franiesbf. the

ten

'1 members D and a member I) to form a fgpt "board for the bed.

Said members D and D are rigidly connected to the seat frame, and whenthe parts are in the compacted seat'formi'ng relations ,the le'g' member D has an upstand ng position-at the back of the chair or couch above the'level. of the seat frame while the foot board member has a depending position below such level.

01 represents a portion of the main frame A, and to an intermediate portion of the back frame C.

6 represents another link connected to a rear portion of the intermediate frame 15; and to an intermediate portion of the link e.

E represents an ai'igular lever pivotally connected to a forward portion of the intermediate frame, the rear arm 7 of such lever being upwardly and rearwardly extended from. the pivoted elbow, while the forward arm 9 of the lover is extended from the elbow with an upward, and forward inclinatioii.

A more or nearly horizontal link I, connects the upper end of the rear arm of the angular lever with an ii'itermediate nortion of the said link A linkage is provided between the upper end of the for ard arm of the elbow lever E and the seat frame 1) adjacent the pivotal connection or hinge i which forms the joint or articulation of the seat frame to the upper forward portion of the intermediate frame B,-the mnnection of such linkage with the seat frame being to the rear of the pivot 2' as the parts are when in the relation shown in Fig.

'Siicli linkage consists of a Short link i'iorinally dou'iiii'ardly and roarwai-dly inclined, as per i and a loi'ig'er link ll: pivoted to the li and having the lower end thereof pivoted to the angular lever arm g. I

- This linkage constituted by the 'ii\-'otally connected iueml'iers j and A: constitute in sub stance a toggle.

The seat frame has at a si'iitalile'i'listance to the rear of its pivoted forward edge :iiiioiulion formed as a laterally projecting stud m to edgcwise ougagotho scat 'li'aineliiik j at times when the s it frame normal FHPOIllYll'iOHGd mental frame. and also when the seat frame is swung fi'o'iii such position to an upward and -i'.(zU' \'2il'(l inclination approaching a v ertical positi n. see Fig. -3 and the dotted D iii Fig. -1.

exertion through the above described system of lever arms and links to cause, as may be additionally assisted bymanual power, the

folding up and moving to. compacted relations of the seat and bed forming frames.

To overturn and open the parts from the relative positions of Fig. '2, the main and i D and D. are swung up to about the relations shown in Fig. 3, and then continued to the overturned position shown in Fig. '4.

The normally rearwardly inclined back frame G and its supplemental frame C exerts a force in a downward direction against the upwardly and fo'rwardly inclined link d to swing the latter forwardly and downwardly.

This has the effect through the link a to impart a thrust in a forward direction to the link h which is connected to the angular lever E and to cause the intermediate frame on which the lever is mounted to he slid in its forwardly distending direction.

T he relief of the counter link and lever system; when the seat frame overtiiri'im'l from the positionof Fig. 3 to that of Fig. 4-, and by reason of the stud I'I'i iiio'viiig away from engagement with the link 9, leaves the completion of the move mBIlts of the intermediate frame and back frame free to be automatically gravitatively perforined,-ivithoiitregard to any manual restraining or assisting foroe,-t'he weight of the back frame C and the supplemental back frau'ie C being the operative factor.

Therefore, the back frame which had normally been in a position slightly rea-rwardly inclined from the vertical will assume a. laid out horizontal position and the supplemental. back frame hinged thereto may be swung up to an a 'iproximately vertical position, and for the time of the use of the.

parts as a bed, held in such position by the confining moans provided therefor, the same, as shown, comprising a foldable brace consisting of two bars n and n pivoted together at their inner ends, and at their outer ends pivotodto the supplemental back frame C and to the back frame proper C.

One of the link-like parts or sections has a. short arm if angularly extending from adjacent the two part connecting pivot and has a spring a", by its one end connected to such arm and by its other cndlto the other member of the liraco,-.tho effect of such spriiu l ning to hold the brace members 'n and ii iii,' or substantially in, their straightciicd lu'aco forming relations.
